Application January 9, 1951, Serial No. 205,158

1 Claim. 1

This invention relates to a binder, and more particularly to a binder or holder for memorandum books, pads, and the like.

The object of the invention is to provide a binder which includes a retaining strip that is held attached to a cover by a back bar,l there being a rod connected to the retaining strip for supporting a notebook or pad-retaining member.

Another object of the invention is to provide a binder which includes a notebook-retaining member that will not accidentally slip off its retaining rod, the leaves of the notebook or pad being held in an orderly manner by the binder of the present invention.

A further object of the invention is to provide a binder which is extremely simple and inexpensive to manufacture.

Other objects and advantages will be apparent during the course of the following description- In the accompanying' drawings forming a part of this application, and in which like numerals have been used to designate like parts throughout the same:

Figure 1 is a view of the binder of thepresent invention, with the cover opened up and holding a pad;

Figure 2 is a sectional view taken on the line 2-2 of Figure l;

Figure 3 is a fragmentary, side elevational view of the binder, with the cover opened up;

Figure 4 is a longitudinal sectional view taken through the assembly of Figure 3;

Figure 5 is a view similar to Figure 3. but with the cover closed;

Figure 6 is a plan view of the .pad-retaining member;

Figure 7 is an end elevational view of the padretaining member;

Figure 8 is a side elevational view of the padretaining member;

Figure 9 is a plan view of the blank for making the pad-retaining member;

Figure 10 is a plan view of the back bar;

Figure 1l is a sectional view taken on the line of Figure 10;

Figure 12 is a side elevational view of the retaining strip;

Figure 13 is an enlarged, fragmentary, perspective view of the retaining strip;

Figure 14 is a fragmentary, sectional view showing certain structural details of the assembly.

Referring in detail to the drawings, the numeral designates a cover which may be fabricated of any suitable material, such as leather,

2 and the cover is adapted to be folded medially between its side edges to form a front and. back cover. The binder of the present invention includes a back bar 2 I, which includes a body por@ tion 22 that has its longitudinal side edges 23 folded back upon themselves, Figure fi, and the back bar 2| is also provided with lips 24 which are adapted to be folded over the side edges of the cover 20 in order to maintain the parts in assembled relation. Suitable prongs 25, Figures 10 and 1.1, extend from each of the lips 24 for engage-"- ment with the cover 2|)v so as to prevent accidental movement of the back bar 2|.. Y

The binder of the present inventionfurtherincludes a retaining strip,r Figures12- and 1,35, and the retaining strip is indicated by the numeral 26. The retaining strip 26 includes an elongated section 21, which is provided with. a pair of upstand ing, arcuate support portions 28T. Each of the support portions 28 is provided with an opening 29, and the ends of the retaining strip 26- areA shaped to provide tongues 3|) whichY are adapted to be bent over the side edges of the cover 2U, as shown. in Figure 14'.,- Whereby the lips` 24 of the back bar 2| will retain the retaining strip 26 immobile in its proper position. It will be seen that the back bar 2| is arranged on one side of the cover 20, while the retaining strip 26 is arranged on the opposite side thereof, these elements bcing arranged in parallel relation with respect to each other. A rod 3| has its ends seated in the openings 29 in the support portions 28, for a purpose to lbe later described.

There is further provided a pad-retaining member which has a substantially U shape, and the pad-retaining member is indicated generally by the numeral 32, Figures 6, '7 and 8. The blank for making the pad-retaining member 32 is shown in Figure 9. The member 32 includes a web 33, and extending from the web 33 is a pair of spaced side walls 34. Each of the side walls 34 includes a straight section 35 and an offset section 36, Figure 7. The end portions of the side walls are bent inwardly, as at 31. to dene lugs, whereby the pad-retaining device 32 will not accidentally work loose from the rod 3|, even though the pad P has been removed from the retaining device 32. In other words, the lugs 31 act as stops to engage the support portions 28 to prevent accidental disengagement of the pad-retaining device 32 from the rod 3|.

The pad-retaining device 32 further includes an open mouth 38. Figure 8, whereby the pad P can be readily removed from the device 32. or when necessary, a new pad can be positioned therein. It will be seen that the ends of the mouth, which are designated by the numeral 39, are wider than the central portion of the mouth 38, so as to facilitate the insertion of new pads P in the device 32.

In Figure 9 there is shown the blank for making the pad-retaining device 32. The pad P is retained between the offset sections 36 by friction, and the blank of Figure 9 shows the crease lines 40 about which the side walls are adapted to be bent to form the web 33, and the straight sections 35 of the side walls 34. There is further shown the fold lines 4| which indicate the place Y where the offset portions 36 of the side walls 34 are folded. Finally, the numeral 42 indicates the fold lines about which the lugs 31 are folded or bent.

In assembling the binder of the present invention, the retaining strip 26 is first arranged contiguous to the inside of the cover 20 at the medial point of the side edges, and then the tongues 30 are bent over the side edges of the cover so that they are in the position shown in Figures 2 and 14. Then, the back bar 2| is arranged on the opposite side of the cover 20 and the lips 24 are bent over the tongues 30 to lock the retaining strip in place, as shown in Figures 2 and 14. The rod 3| is inserted in the openings 29 in the support members 28, and then the retaining device 32 is mounted on the rod 3|, after which the lugs 31 are bent about the fold lines 42, Figure 9, so that accidental disengagement of the pad-retaining device 32 will be prevented. The rod 3| serves as a fulcrum about which the notebook or pad P is pivoted or turned.

The parts of the present invention are so constructed that the retaining device 32 will not accidentally slip off of the rod 3 since the ends of the retaining device 32 will engage the support members 28. Also, once the lips and tongues have been bent to the positions shown in the drawings, accidental disengagement of any of the parts will be prevented, even though the pad P may be removed from the retaining device 32. Also, the retaining device 32 is constructed so that the loose leaves or pads will be maintained in an orderly position. The prongs 25 bite into or engage the cover 20 so that the back bar 2| will be maintained in its proper place.

What is claimed is:

In a binder. the combination which comprises a cover folded midway between the ends providing a front and a back, a retaining strip having upstanding U-shaped support portions spaced from the ends and said support portions having inner and outer sections with their extended ends connected with arcuate portions, the inner sections of said support portions having rod receiving openings therein, means securing said retaining strip to the cover, a pad retaining member, U-shaped in cross section, having a web with spaced side walls extended from the edges thereof positioned with the web and adjoining portions of said side walls between said upstanding portions of the retaining strip, and a, rod extended longitudinally through said pad retaining member and positioned with the ends thereof freely held in the openings of the inner sections of said upstanding support members, the ends of the side walls of said pad retaining member being extended beyond the ends of the web thereof and having inwardly bent lugs on edges thereof, said inwardly bent lugs being in a plane spaced from and parallel to said web whereby the lugs are positioned to engage the upstanding U-shaped portions of the retaining strip to prevent accidental separation of the pad retaining member from the binder.
